Hoosiers, having been spoiled by this week's near-record warmth, will get a rude awakening beginning Friday, as the leading edge of a vast pool of chilly air pours over Indiana.
This chilly air promises to bring Indiana its lowest temperatures of the season thus far.
Temperatures Friday will hold up to 25 degrees below the balmy upper 70s and lower 80s reached on Thursday.
Put another way, highs will be in the lower to mid-50s in most of northern and central Indiana.
Indianapolis hit 78 degrees on Wednesday, and was expecting at least as high on Thursday. Friday's forecast was for a high of 54 degrees under rainy skies.
The agent for change, a cold front plowing into the Midwest from the Great Plains, will cross the Hoosier State with a band of rain and even thunderstorms Thursday night and early Friday.
Slowing of the front west of the state will allow rainy weather to linger in the afternoon in central and eastern Indiana.
Meanwhile, the coldest weather will not begin until early next week, when all but southernmost Indiana can look forward to highs in the 40s.
Following midweek warmth, dry and more seasonable weather is expected across northern Europe early this week.
Ahead of the monsoon season in India, temperatures will swell well above normal in parts of India and Pakistan.
A storm system responsible for severe weather across the Plains over the past week, as well as the snow across the Rockies will advance eastward.
The Highway Fire started around 6:10 p.m. PDT Saturday near Corona, California, in the Prado Dam area in Riverside County, and grew from 30 to 175 acres in a matter of three hours.
A pattern favoring waves of progressively cooler air will set up across much of the Midwest and Northeast during this week and could continue into early May.
Round after round of drenching rain will continue to cause flooding in the South, while another dose of rain may renew flooding in the Ohio Valley this weekend.
